Referring more particularly to the single type or embodiment ot my. invention herein illustrated. the engine herein represented is provided with a easing and an internal memher, herein tor convenience of descrips tion termed a rotor. In the practice ot' my invention, I impart a relative rotary movement to the casing and rotor. Movement ot .rotation may he imparted to either the casing or the rotor. In theA present type ot' theinvention. however7 I have represented the rotor as mounted jt'or rotation within the casing. which herein is stationary.

The easing wherein the rotor is mounted may he or' any suitahle outline in cross tion. heing either circular or non-circular. as is 'lound liest adapted to the particular requirements ol the type o't' engine wherein my invention` is ei'nployed. YReferring more particularly to l `igs. .4', 5 and l(5, the easing, which herein is represential as substantially circular in cross seetion and as Stationary, is rel'n'eseiated at 1. it -heing adapted to l'ereive therein for rotary motion a shaft 2 mounted in suitahle Yhearings 2l, representful most clearly in Figs. l and Mounted within the easing Vl upon the shaft 2 is a` rotor l oi' any suitable type. and inclosing thi` rotor within the easing are provided suirahle heads 5 aml (3. hotli o t which are preferably removahle `from the easing l. 1While in the specification and claims l relier to'one or more heads. it is to he understood that one ol the heads may he integral with or iorm a: portion ot the easing. and the claims are to he construed in view ot this statement.

While .I may secure the heads 5 and (i t0 the rasingl in any suitable manner and may eonstruet the heads in the torni that is iound most desirahle. herein (see Fig. (i) l extend a portioii T ol' each head into the casing l at opposite sides thereof. it heing apparent that a portion or the whole ot either or hoth heads may he received within the easing. In lhe present type ol the invention, however. nl have reprewnled eaeh olE the heads as ha ving a portion extending into'the easing aud au encircling rim H adapted to he positioned adjacent the ends ot' the easing. The portions T of the heads should, to secure the liest results. he tLgfhtly fitted within the easing where contacting with the inner tace oli the easing. \Vhile either or both ot' the rims 8, which lor the hest results should he continuous. may he tightly fitted against the opposing ends oi the easing l. prelerahly and as most clearly rel'n'esented in Figs. Jr, (i and T l so construct one or hoth o'l: the heads as lo permit` the taking up ot' wear hetweeu the head and the rotol 'and the part or parts assoeiated with the latter. YVhile masses this vmay be accomplished in any desired manner, preferably l 'provide bolts 9 (see Fig. i9) passing through the rim 8 of each head and tapped into the ends of the casing l, whereby said rims may be drawn into the desired relation with respect to the casing., the rims 8 of the said heads being, when the parts are assembled, preferably spaced somewhat from the adjacent ends of the casing l, the extent of which spacing may be determined in any suitable manner, as, for eX- arnple, by the provision of means limiting the movement of the said rims of the head towand the ends of the casing. To that end, in Figs. l and 19, l have represented set screws l0 Atapped into the rims S with their inner ends 4projecting beyond the inner faces of said rims and into contact-with the ends of the casing or other part positioned thereagainst. lf desired, a gasket or the like l2 may be introduced between the ends of the casing l and the rims 8, .with `which the limiting screw-s1() may contact. lt is apparent that by adjusting the screws l0 as desired I may determine the entent of inward movement of the rims 8 of the heads toward the casing l. Not only do the set screws tend to limit the inward movement oit the rims but they act to hold the said rims in their predetermined position.

l contemplate the provision of means whereby l may position therotor with respect to, the casing,` and also the provision means `for taking up wear between the L. k vic ng a tight joint between them. This may oe accon' Ished in any desired manint o'f the invention, I rdly projecting surface vor may 'ft/ined integral with J heads of the casing or operaoie t creto in any suitable mansurfaces may be el any desired shape, being formed by the revolution of a'straight, irregular or curved line about an axis, and thus being of desired cylindrical form or of any other suitable formation. ln the present embodiment oi" the rinvention, l show lli desired., any suitable form bearingas, for example, ball'orroller bearings may be employed between the bearings 3 and the Ashaft 2. While the bearings 3 'may be formed lntegrally with the heads 5 and 6, preferably they are formed separately .there rotor and the heads of the casing; whilepro-u Ldiy projecting surface or such inwardly projecting surfaces as taperfrom and are received within approximately central openings 13 formed in said heads 5 bearings and tapped into the adjacent portion ol' the heads 5 and 6.V The rims l5 may be suitably spaced from the head to permit the takingup of wear between the conical surface and the rotor, and to that end l may employ means such as described for taking up wear and to provide packing between .the heads and the' casing, employing if desired limiting and holding set screws and a gasket such as shown at l2 or any other device accomplishing this end.v Itis .apparent that the construction of parts may be reversed and that the tapering portion may be formed upon or connected to onejor both end faces of the rotor, to be received within a correspondingly recessed portion of each head or heads. Y

While each bearing 3, if formed separately from the Yheads 5 and (3, may be integrally formed by casting or otherwise, preferably each of said `bearings is formed of 'a plurality 'of parts, since in this type of the invention l contemplate providing a chamber or .chambers within each bearing for the introduction of the motive agent` or agents, which chambers may be more readily provided by forming said bearings of a Vplurality of parts. Inasmuch as I contemplate, it de sired, the introduction of a plurality of' different motive agents through said bearings, I suitably form a corresponding number 0f chambers. To that end, l herein provide an inner sleeve like member 1G serving as the bearing proper for the shaft` 2, the inner end thereof being frusto conical in shape, as previously described, each bearing in cross section being of a general T-shape to provide for the reception thereon of the` secondary member'l?, between which and the inner sleeve is provided the chamber or chambers referred to. Preferablythe sleeve 16 is screw threaded, as represented 'at '18 and 19, to receive thereon the secondary member l?. ln any suitable manner Within the bearing or bearings 3 I provide one or more chambers `for a motive agent or agents, which may be of any suitable nature as previously stated. Preferably, however, land in this form of the invent-ion, I provide av i main chamber 20 in each bearing-which for convenience oic constructionpis provided between the sleeve 16 and the secondary mem-r ber 17. Vihile any suitable -Lrnotive'agent be introduced 'into this chamber, I herein contemplate the introduction of air, preferably under suitable pressure, or, if the motive agents are mixed outside of the engine, a suit-able inist-nre of air and some explosive agent. rllhe air or a mixture, if` desired, is introduced into each 'chamberQO
